Stocks: Tech earnings to dominate

Investors are heading into the shortened trading week with a deluge of technology focused quarterly financial reports on tap.

U.S. markets will be closed Monday in observance of Martin Luther King, Jr. Day.

Earnings season will pick right back up again on Tuesday, as several tech giants, including Google(GOOG), IBM(IBM) and Verizon(VZ), release their quarterly reports.

The barrage of tech earnings will continue throughout the week, with AT&T(T), Microsoft(MSFT), Netflix(NFLX) and Nokia(NOK) following.

The most hotly anticipated report will come from Apple(AAPL) on Wednesday.

2012: The year the PC died?

The iPhone and iPad maker already warned that its profit margins would come down significantly during the final three months of the year thanks to higher production costs tied to all of its new products, including the iPhone 5 and the iPad mini. Less-expensive products, like the iPhone 4S and iPad mini, also make up a growing portion of Apple's sales mix.

While expectations are all over the map, some analysts anticipate a year-over-year decline. That would mark Apple's first drop in profits in nine years.

Overall, S&P 500 companies are expected to report earnings growth of 3.8% for the last three months of 2012, according to S&P's Capital IQ.
